Digitally adjustable evaluation units

Temperature monitoring relays distinguish themselves

due to the fact that they are extremely easy to operate.

The actual temperature is always displayed on the three-

digit LED display. A dedicated relay with one NO contact

is integrated to monitor the sensor.

The relay is switched-off in the parameterizing mode.

The following parameters can be set:

• Sensor type

• 2 threshold values J

, J

• 1 hysteresis; this acts on both thresholds (0–99 K)

• 1 delay time; this acts on both thresholds (0– 999 s)

• Either the open-circuit/closed-circuit principle can be

selected

• Function: Overtemperature/Undertemperature

(overrange/underrange) or window monitoring within

a defined range

Versions with a wide-range voltage have electrical

isolation.

The temperature ranges are dependant on the sensor

type (refer to the function).

The short-circuit and wire breakage detection, as well as the

measuring range are restricted, depending on the sensor type:
